The Difference Between IRPR and Generic Dev Shops
Not all backend development agencies deliver the same quality.
Generic dev shops often hand you code without documentation or tests. Then they disappear or charge hourly for every change. Your backend becomes a maintenance nightmare.
IRPR is different. As leading backend app development developers, we ship production-ready backends with documentation, tests, and monitoring. Our fixed price model means no surprises. We stand by our work with 30 days of post-launch support.
- No documented API
- No automated tests
- No CI/CD pipeline
- No post-launch support
- Hourly billing with scope creep
- Unknown compliance status
- OpenAPI documentation
- Unit and integration tests
- GitHub Actions CI/CD
- Sentry monitoring and 30-day support
- Fixed price from Roadmap
- HIPAA, SOC 2, PCI-DSS compliant
Our Backend Development Process
From idea to production in 12 weeks, with clear milestones.
Every backend project at IRPR, a leading backend app development developer, follows a proven process. We start with a 2-week Roadmap to define scope, architecture, and fixed price. Then we design, build, and deploy in sprints.
You see working code every two weeks. You own the code from day one. We handle deployment, monitoring, and documentation so your team can take over easily.
